“…Monounsaturated fatty acids, however, increased markedly during the same period (Tables 2 and 3 (Chehade et al, 2016). In sunflower and safflower, a decrease in both oleic and palmitic acids was noticed during ripening (Gouzy et al, 2016;Roche et al, 2016;Merah et al, 2012).…”

Petrosellnlc acld Oil content Llpld accumulatlon Rlpenlng stage C.Oriander contains petroselinic acid, an isomer fatty acid of oleic acid. C.Oriander seed oil bas been proposed as nove! food ingredient in the European Union. Field experiments were performed at Auch (France) during two seasons (2010 and 2011). From flowering to maturity, fruits were barvested weekly and oil content and fatty acid (FA) compositions were determined. Fruits presented 2% more oil in 2010 tban in 2011. Petroselinic acid (PA) contents was higher in 2011 tban in 2010. Oil accumulation began earlier after flowering (2 DAF) in 2011. A first step in accumulation was identified between two and 21 DAF characterized by bigb SFA and PUFA, wbicb decreased 21 DAF. Subsequently, PA increased to its highest concentration (30-55 DAF) and SFA and PUFA reacbed their Jowest. These results suggest that bigber concentrations of PA can be acbieved by collecting fruits before full maturity.

“…Delaying the sowing date induced a decrease of unsaturated fatty acids in our experiment. Environmental effects (temperature or water regimes) have already been described to impact significantly the seed composition of several oil crops [23][24][25]. More recently, the effect of intercepted solar radiation was reported.…”

“…Lindsey et al [34] have reported, in Arabidopsis mutants, that overexpressing SMT-2 results in higher accumulation of β-sitosterol highlighting the involvement of this enzyme in the regulation of sitosterol/campesterol balance. Through the activity of the SMT-2 enzyme, results on safflower indicated that it may be possible to modify the sterol and fatty acid contents and composition by cultural practices management [25,26]. In terms of the distribution of phytosterols in the seed, the stigmaterol was the only sterol that presented a higher concentration in the hull compared to the embryo.…”

Field experiments were carried out at the Regional Centre of Experimentation in Organic agriculture at Auch (near Toulouse, South west of France). Due to the high potential applications for its oil components such as fatty acids and phytosterols, safflower (Carthamus tinctorius L.) is considered as an emerging crop. Safflower plants, as many other oil crops, are submitted to environmental stresses that modify seed composition. Nevertheless, few reports are available about the effects of environmental conditions on fatty acid and phytosterol compositions in safflower. Different rainfall supplies can be managed by delaying the sowing dates. In this study, fatty acid and phytosterol contents have been evaluated in safflower seeds cultivated at two sowing dates (conventional and late) that led to a differential of rainfall during seed development. At harvest, seeds were used for oil extraction. Fatty acid composition was performed by using GC-FID. A set of seeds was dehulled to separate the almond (embryo) and hull to release the extraction and measurement of sterol contents in the two compartments by GC-FID. A delay of sowing increased the content of all sterol categories but induced a significant decrease in fatty acids. The ratio of saturated to unsaturated fatty acids increased under a delaying sowing. The repartition of phytosterols was ¾ and ¼ of total sterols in the embryo and the hull, respectively. These results could make the use of hull (considered as waste) possible, help breeders to improve safflower oil composition and develop new industrial applications.

“…Oil from HO sunflowers bearing Pervenets mutation shows a fatty acid profile characterized by 80–90% oleic acid, 1–10% linoleic acid and almost undetectable linolenic acid content (lower than 0.3%) (Table 1). Even for the highest oleic acid values, HO sunflower hybrids show no significant difference in grain yield, oil content, and seed productivity when compared to conventional sunflower hybrids (Angeloni et al, 2017; Carvalho et al, 2019; Fick, 1984; Gouzy et al, 2016; National Sunflower Association, 2018; Van der Merwe et al, 2013).…”

Dietary trans fatty acids (TFA) from industrial partial hydrogenation continue to occupy the attention of health and regulatory authorities, prompting renewed recommendations and regulations around the world. Partial hydrogenation of liquid oils was widely used because it increases the oxidative stability and plasticity of vegetable oils. The development of high oleic (HO) oils appeared as an efficient and healthy strategy to replace partially hydrogenated vegetable oils. At present, the main sources of HO oils are the HO varieties of sunflower, canola, and soybean, covering almost the entire market. Although all these HO crops show oleic acid contents higher than 70%, they can be differentiated by their fatty acid profiles. Recent clinical evidence suggests that polyunsaturated content should also be considered since its intake has been associated with coronary heart disease. Comparison of the fatty acid compositions, places HO sunflower as the best option in terms of oxidative stability and beneficial effects on the health of consumers.
